Abstract
BACKGROUND AND PURPOSE: The Babinski Reflex, first described in 1896, is still an integral part of the neurological examination. Many have studied the consistency of this reflex, but none have compared the inter- and intra-observer consistency of the Babinski reflex and its variants. METHODS: Thirty-four subjects were examined by six neurologists. The Babinski, Gordon, Chaddock, and Oppenheim reflexes were tested, and each neurologist concluded if the plantar response was flexor or extensor. Six subjects were re-tested 1 week later to determine intra-observer consistency. RESULTS: The Babinski reflex had the highest interobserver consistency with a kappa value of 0.5491. The Chaddock, Oppenheim, and Gordon reflexes had kappa values of 0.4065, 0.3739, and 0.3515, respectively. For intra-observer consistency, Gordon was the most consistent with a kappa value of 0.6731. When reflexes were combined in pairs, the Babinski and Chaddock reflexes together were the most reliable. CONCLUSIONS: The Babinski reflex was shown to be the most consistent between examiners. The Gordon reflex had the highest intra-observer consistency; however, the small sample size should limit conclusions drawn from this calculation. Clinicians often utilize more than one reflex to examine the plantar response; the combination of the Babinski and Chaddock reflexes was the most reliable.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
